PRODUCTIVE DEPOSIT DEVELOPMENT METHOD Russian patent published in 2014 - IPC E21B43/16 E21B43/11 

FIELD: oil and gas industry.

SUBSTANCE: productive deposit development method involves study of a zonal non-homogeneity degree of a productive deposit and its non-homogeneity as per thickness using carbon-oxygen logging, performance of interval-by-interval selective perforation of the productive deposit in the well according to non-homogeneity degree of the above deposit. For that purpose, interval-by-interval filtration model of the borehole environment is created, which considers its interval fields of porosity, oil saturation, permeability, rock anisotropy, and the combined filtration model of combined filtration of fluids to the well throughout the thickness of the productive deposit. Coupling factor of each certain well interval with the productive deposit as a whole is determined. After that, development area of each interval of the productive deposit is determined as per its thickness in compliance with analytical relationship. Then, the following is performed: well perforation using the obtained data on the development area of each interval of the productive deposit with cumulative charges, well development and its further operation.

EFFECT: increasing oil recovery factor of a productive deposit and reducing its development period.
